CARPET-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 620,782, dated March 7,1899.

Application filed November 19, 1898. Serial No. 696,852. No model.)

To (all whmn it may concern.-

Be it known that I, LEOPOLD KERN, a subject of the Czar of Russia,residing at Hillsborough Bridge, in the county of Hillshorough and Stateof New Hampshire, have invented certain new and useful lm provements inCarpet-Fasteners, of which the following is a specification.

This invention relates to an improved carpet fastener, by which thecarpet can be readily applied to the floorand removed therefrom forcleaning without the use of tacks; and the invention consists of acarpet-fastener comprising a permanent socket-section provided with ashank, a solid head portion above said shank, a hollow perforated headportion at the side of said solid head portion, and a cap-sectionprovided with a threaded shank adapted to engage the head of saidsocket-section at its perforation, and, further, in certain details ofconstruction and arrangement of the parts to be more fully describedhereinafter and finally claimed.

In the accompanying drawings, Figure 1 represents a floor, showing anumber of permanently-applied socket-sections of my improvedcarpet-fastener arranged at suitable locations thereon. Fig. 2 is a planView of a floor with a carpet laid thereon and held in position bymyimproved fasteners. Fig. 3 is a vertical transvere section on line 33, Fig. 2, drawn on a larger scale and showing the method of attachingthe carpet to the floor by means of my improved fastener. Figs. 4 and 5are respectively a top view and a vertical central section on line 5 5,Fig. 4; and Figs. 6 and 7 are a top view and a vertical central sectionon line 7 7, Fig. 6, of the detachable portion of my improved fastener.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the lower or socket section ofmy improved carpet-fastener, and B the detachable cap portion of thesame. The lower section A is provided at one side of its center with anail or screw shank a and with a solid head a above said shank. Theremaining portion of the head of the socket-section is made hollow andprovided with an opening a The solid portion a of the rounded-off headof the socket section a is smaller than the hollow portion.

' The solid portion a is provided with a transverse nick a by which theshank can be screwed into the floor if a screw-shank is used, as in Fig.5. Then an ordinary nailsha-nk is used, as in Fig. 3, the socket-sectionA is driven into the floor by a hammer in the usual manner. Therounded-off socket-section A, with its solid and hollow head portionsand its shank, is preferably made of cast metal and is secured to thefloor nearthe wallin such a manner that the hollow portion in the headis located toward the wall, as shown in Fig. 3.

The detachable cap portion B is formed of a convexo-concavo cap of sheetmetal, to which is attached a central coarsely-threaded shank b, asshown in Fig. 7. Before the carpet is laid the socket-section A isdriven into the floor near the wall. The edge of the carpet is placedover the head of the socket-section A and the threaded shank of the capportion pressed or screwed through the carpet, so as to enter throughthe opening a into the lower hollow portion of the head of the sectionA, as shown in Fig. 3, in which position the shank b engages the edge ofthe opening a and the shank of the socket-section A, retaining thecarpet firmly in position thereon due to the strain exerted by thecarpet in the shank of the cap-section and the head of thesocket-section. The location of the head of the socket-section on thefloor can be readily ascertained by placing the carpet over the same andfeeling with the finger for the head, after which the shank of the capportion is forced through the carpet either directly or by giving thecap-section a few turns until the above connection with the head of thesocket-section A is obtained. WVhen the capsection is placed inposition, the strain of the carpet establishes the connection betweenits shank and the head of the socket-section A,

so that the cap-section cannot be released therefrom, the edges of theopening in the adjacent solid portion biting on the coarse threads ofthe shank and retaining the same against the tension of the carpet. Whenit is desired to take up the carpet, the cap-section is removed byturning it on its axis. As soon as the cap portion is released from thestationary section it can be withdrawn from the carpet and the latter betaken up.

By my improved carpet-fastener carpets can be laid down or taken up in aquick and convenient manner without special tools and without the use oftacks. The fastener can be furnished at a very low price.

The carpet-fastener can bemade in different sizes and of differentmetals, the cap-section being preferably made ornamental,as the same isvisible,while the socket-section,which is covered, does notrequire anyextra finish.

I am aware that a carpet-fastener consisting of two sections, one ofwhich is permanently attached to the floor and the other con nected bysuitable fastening means to the socket-section, is old. I do not claimsuch a fastener; but I am not aware that the special construction shownby me by which the sections can be applied without special tools hasever been used before my invention thereof.

Having thus described my invention, 1 claim as new and desire to securebyLetters Patent 1. A carpet-fastener, consisting of a permanentsocket-section provided with a shank, a solid head portion above saidshank, and a hollow perforated head portion at the side of said solidhead portion, and a cap-section provided with a central threaded shankadapted to engage the head of said socket-section at its perforation,substantially as set forth.

2. A carpet-fastener, consisting of a lower or socket section, composedof a shank at one side of the center, asolid head portion above saidshank, and a hollow and perforated head portion at the side of saidsolid head portion, and a cap-section provided with a central threadedshank adapted to pierce the carpet and engage the hollow portion of thesocketsection, substantially as set forth.

3. In a carpet-fastener, a lower or socket section composed of a headsolid at one part and provided with a shank below said solid portion,and a hollow portion of larger size than the solid portion and providedwith a perforation, substantially as set forth.

4. In a carpet-fastener, a lower or socket section provided with a shankon one side of the center line, a solid portion above said shank, and ahollow portion of larger size than the solid portion and at one side ofthe same, and provided with a perforation in its apex, substantially asset forth.

In testimony that I claim the foregoing as my invention I have signed myname in pres ence of two subscribing witnesses. I

LEOPOLD KERN.
